This is a modified Windows 7 driver for the Panasonic CF-18 Tablet Toughbook. Be sure and use DriverMax to import these drivers into your fully updated copy of Windows 7 SP1. The video driver will install cleanly and correctly when you use this recommended "freeware" utility. If you have seen online, the only other workaround is to install the secondary video as a 915gm/gme. After hours of coding and I have an xp primary and XDDM Vista secondary of the same chipset. There is a manual rotation registry key available online as well.
